A hiker who can negotiate difficult terrain with ease is called surefooted.
A surefooted hiker isn’t one who carefully studies the rocky path ahead of her and plans out every step in advance. Instead, a surefooted hiker jumps right in and takes each step on the fly, springing and landing with a cat’s grace. The sureness lies not in advance planning but in being nimble, agile and flexible to make adjustments as necessary.
The surefooted among us are adept at making the most of leaps that are rather unsure.
